Haemophilus Chocolate Agar Selective Medium (Chocolate Agar Plate (Dual Antibiotic)) is a specialized culture medium designed for the isolation and cultivation of clinically fastidious bacteria. Through the dual action of its nutritional support system and selective inhibition mechanism, it significantly enhances the detection rates of target pathogens such as Haemophilus influenzae and Neisseria gonorrhoeae, while effectively suppressing interference from contaminants like Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. Neisseria meningitidis, and Neisseria gonorrhoeae while effectively suppressing interference from contaminants such as Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa.
